Description

The order of what is displayed in front vs behind is incorrect with 3D elevation.
A mountain behind another would appear in front it with a southern hemisphere pole.

Script attached that creates 4 figures (only changing azimuth in -JOA).
The last one (where the top of the map is in a south direction) has order of what is displayed in front/back wrong.
